claude-hdb a10349d835 feat: cast — the Coolify executor, extracted from the infra state repo
Public tool, private state. cast holds no hostnames, no bindings, no
secrets: it joins a product repo's .infra/ manifest with a state directory
you point it at, and makes Coolify match.

Extracted from heavy-duty/infra, which was half tool and half state — the
inconsistency that made it impossible to say whether "infra" named a CLI
or a runbook. rig builds the boxes; cast fills them; infra is what they
are filled with.

Two changes were required to make it genuinely stateless and publishable:

- The implicit cwd contract (environments.yaml / secrets/ / .coolify.env
  resolved against the working directory, silently reading the wrong file
  from the wrong place) is now an explicit --state <dir> / $CAST_STATE.
- BANNED_IN_PROD — a hardcoded list of one product's ALLOW_* flags, the
  only product knowledge in the executor — becomes the generic, operator-
  owned environments.<env>.forbidden_var_patterns. The guard now lives in
  private state, so a product-side change cannot lower its own guard, and
  it is a pattern rather than a list, so it catches unforeseen siblings.

Age identities resolve as $CAST_AGE_KEY_FILE_<ENV> then
~/.config/cast/age-<env>.key — which is the entire attended-vs-unattended
apply mechanism, with no environment names known to the tool.

Instance identity (org names, the GitHub App name, founder domains) is out
of the fixtures and out of register-github-app.sh, which took APP_NAME and
ORG as arguments rather than baking them in.

69 tests green; bin/cast + curl installer mirror rig's shape.
